Ultra Rapid Hardening Concrete Composition and Road Concrete Repairing Method Using The Same
The present invention relates to ultra rapid hardening concrete composition and a road concrete repairing method using the same. The ultra rapid hardening concrete composition includes 10-20% by weight of ultra rapid hardening, 0.5-1.0% by weight of activated silica, 1.0-5.0% by weight of liquid latex (40-50% by weight on a solids basis), 40-50% by weight of sand, 30-40% by weight of aggregate, and 5-0% by weight of water. The composition ratio of activated silica and liquid latex is 1:2.4 to 1:3.0 by weight.
본 발명은 초속경 시멘트 10~20 중량%, 활성실리카 0.5~1.0 중량%, 액상 라텍스 1.0~5.0 중량%(고형분 기준 40~50%), 모래 40~50 중량%, 골재 30~40 중량%, 및 물 5~10 중량%를 포함하되, 활성실리카와 액상 라텍스의 조성비가 중량비로 1:2.4~1:3.0인 것을 특징으로 하는 초속경 콘크리트 조성물 및 이를 이용한 이를 이용한 콘크리트 도로 보수방법을 제공한다.
